RCMRT 5 MGM ATTORZVEY Patented Aug. 14, 19 51 HINGE Robert S. Wagner,Milwaukee, Wis, assignor to E. R. Wagner Manufacturing Company,Milwauliee, Wis, a corporation of Wisconsin Application November 18,1944, Serial No. 564,017

This invention relates to improvements in hinges, particularly of thetypes which are selfsecuring upon being applied, and to the method ofapplying such hinges to the members which are to be hinged.

While it is desirable from the point of view of strength and appearanceto insert or imbed the leaves of a hinge into the bodies of the membersto be hinged and hold such leaves by friction, certain disadvantageseXist which heretofore have offset such desirableness. In the firstplace, it is difficult to hold the hinge and properly insert the leavesunder pressure, at least without using numerous and time-consuming stepsin the process. Secondly, in order to permit the members to swing apart,one edge of a member must be provided with a continuous rabbet which isunsightly as well as costly to provide.

One of the objects of this invention is, therefore, to provide a hingewhich may be quickly applied to the members to be hinged and securelyfastened without the use of separate fastenings.

Another object of the invention is to provide a hinge which can be usedto hinge two members in edge-to-edge relation without requiring acontinuous rabbet in an edge of one or both of the members.

A further object is to provide a hinge which can be applied in oneoperation to both members to be hinged.

Astill further object is to provide a method for holding the hinge sothat both members to be hinged may be applied simultaneously to thehinge.

The foregoing objects are accomplished by inserting a backing-up toolbetween the leaves of the hinge in such a manner that the frictionalengagement therebetween will hold the hinge on the tool, and formingfrom said leaves, adjacent the pintle bearing, oppositely projectingsecuring portions. 'It is preferable to secure the leaves to the pintleso that when in substantial parallel superimposed position they arespaced to flatly receive therebetween and frictionally engage the fiatend of the backing-up tool. The securing portions are provided with anumber of protruding barbs which frictionally engage the "sides ofroutings formed in the edges of the members to be hinged. The frictionalengagement between the leaves and the tool will hold the hinge on thetool so that the members to be hinged can be pressed simultaneously intothe substantially alined securing portions. By arranging the spacing ofthe routing from the outer surface of the members to be hinged, thepivotal axis of the 3 Claims. (01. 16 -159) hinge can be placed so thatthe amount of the opening or backward swing of the hinged members can becontrolled. Instead of the continuous rabbet usually required, thereneed be only a mortise sufliciently large to accommodate the leaves andpintle bearing of the hinge. The leaves thus perform two functions. Theyprovide a bearing surface whereby the hinge can be mounted on abacking-up tool for insertion, and they position the pintle pin and axissufficiently near one edge of the members to permit them to swing apartwithout the use of a continuous rabbet in one or both edges of thosemembers.

With the foregoing and other objects 'in'view, developed by thefollowing description, the invention consists in certain noveladvantageous structural organizations and features, as well ascombinations and sub-combinations, as more fully explained hereinafterand specified by the following claims.

Referring to the accompanying drawing forming a part hereof, Figure 1 isan enlarged fragmentary view in front elevation of a hinge embodying theinstant invention. For the sake of J clarity the hinge has been showninserted in hinged members, a sectional view being taken on themeandering line Il of Fig 2;

Figure 2 is a sectional View taken on the line 2-2 of Figure 1 withcertain portions of the hinged members removed;

Figure 3 is a sectional View of a box and cover with a hinge embodyingthe instant invention inserted in and secured to the box and the coverto hinge these members, and a view in side elevation of the backing-uptool used in inserting the hinge;

Figure 4 is a fragmentary sectional view of the hinge showing a slightmodification; and

Fig. 5 is a perspective view of the hinge having the slight modificationshown in Fig. 4.

Without intending to so limit the application of the hinge embodying theinstant invention, it is shown as an example inserted in and secured tothe body I and the top 2 of a wooden box 3 of the type used forcontaining jewelry and other small personal objects. In this example amortise 4 is made in the edge of the back of the body portion l andaccommodates the pintle bearing of the hinge. Both backs of the body land top 2 are provided with vertically positioned and alined routings 5into which the respective leaves of the hinge are inserted. This routingmay be prepared by a small circular saw having a thickness less than thethickness of the leaf of the hinge.

'The hinge comprises two leaves designated respectively 6 and I whichare pivotally interconnected by a pintle 8 and preferably arranged sothat when the leaves are in substantial parallel superimposed position(as shown in Figure 2) they will be spaced to receive and flatly engagethe end of a backing-up tool. This is accomplished by forming the pintlebarrels of each leaf so as to be substantially tangential to the leaf.Hence when the leaves 6 and I are in the parallel relationship shown inthe figures they will be spaced by the thickness of the pintle 8. Theleaf 6 is provided with a securing portion 9 formed upwardly as shown inFigure 2 from the body of the leaf to assume a position substantiallynormal thereto. The securing portion 9 is spaced from the pintle orpintle bearing 8 and is provided with protruding barbs It, the purposeof which will be hereinafter described. One way of forming the securingportion 9 is shown in the modification viewed in Figure 4. A U-shapedoutline II is cut in portion 9 which causes a tab Ila to remain as anextension of the leaf 6 when the portion 9 is formed upwardly about aline passing through the ends of the U. The leaf 1 also has formeddownwardly therefrom, as viewed in Figure 2, a securing portion [2. Thisportion I2 is also provided with barbs l and is positioned substantiallyin alinement with the securing portion 9, as shown in Figure 2. It, likesecuring portion 9, may be provided with a U-shaped outline l3 cuttherein which leaves a tab 130. as an extension of the body of the leaf1 when the securing portion I2 is formed downwardly about a line passingthrough i the ends of the U. The tabs Ila and lim make the junctionbetween the leaves and the securing portions more rigid and also provideadditional backing-up tool engaging surfaces. It is preferable toprovide the securing portions 9 and i2, respectively, with a smallsemi-circular projection [4 which acts as a guide finger in insertingthe securing portions in the routings 5 of the box members.

As is shown in Figure 3, a backing-up tool I5 is used in assembling thehinge to the box members. This tool is substantially the same width asthe width of the respective hinge with which it is use-cl in theapplication thereof. Its backingup end (the left end, as viewed inFigure 3) is flat and substantially the thickness of the distancebetween the inner surfaces of the leaves 6 and I when they are insubstantially parallel superimposed position. The right hand end, asviewed in Figure 3, of the backing-up tool [5 is made thin so that itwill cause only a very slight opening between the front edges of thebox. The hinge is frictionally held on the end of the backing-up tool l5by the flat engagement between the surfaces of the leaves and the tool.In some cases it is advantageous to niagnetlze the tool to help hold thehinge. By the manipulation of the tool, the hinge can be positioned andheld so that each securing portion is in alinement with a respectiverouting. With the hinge so held, the guiding projections I4 are insertedin the respective routings 5 of the body l and top 2 of the box, andthese members are thereupon forced together under pressure asserted inopposite directions. This drives each of the securing portions 9 and I2into the routings, and the barbs l0 frictionally engage with the sidesof the routings 5. Thus in one operation the hinge is positioned andrigid- 1y secured in place. If more than one hinge is to be utiliz-d,the tool may be provided with 4 two or more hinge-engaging portions andboth hinges simultaneously secured.

By adjusting the distance of the routings 5 from the outer side of thebody I and top 2 of the box, the axis of the pintle 8 will be adjustedrelative to these sides; With the axis of the pintle positioned as shownin Figure 3, the top of the box can be swung back on the hinge to theposition shown in the broken lines, in which position the bottom backedge of the top 2 engages the top back edge of the body I and preventsfurther backward swinging of the top. If it is desired to permit the topto swing further back, it is only necessary to change the positioning ofthe routings 5, so that the axis of the pintle 8 is moved further to theleft, as viewed in Figure 3, thus decreasing the distance between theaxis of the pintle 8 and the back edge of the box.

It will be seen from an inspection of the drawings that the box andhinge as assemble-d present a very neat appearance. At the most, only asmall portion of the barrel is visible, and there is a substantialedge-to-edge relationship between the top I and bottom 2 broken only bythe small mortises i necessary to accommodate the barrel of the hinge.The engagement between the securing portions 9 and I2 and theirrespective barbs I 0 with the surfaces of the routings 5 is more thanadequate to maintain the hinge rigidly fixed in place. This method offastening the hinge also eliminates the additional steps of adding othersecuring devices, such as nails or screws, and also prevents thebreaking and cracking of the fibres of the wood or other materialusually occurring when additional fastening devices are used.

Although only several embodiments of the invention are shown anddescribed herein, it will be understood that this application isintended to cover such other changes or modifications as come within thespirit of the invention or scope of the following claims.
